LENS-FASTENING- FOR LAMPS.

Specification of. Letters Patent.

Patented Aug. 27, 1907.

Application filed November 20,1905. Serial No. 288,194.

To all whom it mag concern:

Be it known that I, EnNEsT O. EVERETT, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented a new and useful Improvement in Lens-Fasten ings forLamps, of which the following is a specification.

This invention relates to that class of lamps which are mainly designedfor use on vehicles, for instance,

automobiles, and which are provided at the front with a lens or bullseye for concentrating the light, increasing the illumination orrendering the signal effect more pronounced.

The object of this invention is to connect the lens or bulls eye to thesurrounding frame in such manner that the lens can be readily attachedor removed and can be nicely adjusted, as the position of the flame orother conditions may render desirable.

In the accompanying drawings: Figure 1 is a front elevation, partly insection, of a vehicle lamp provided with my improvement. Fig. 2 is alongitudinal section, on an enlarged scale, of the lens or bulls eye andconnecting parts. Fig. 3 is a sectional view, on a greatly enlargedscale, of one of the adjustable supporting rods of the lens. I

Like letters of reference refer to like parts in the several figures.

A represents the body of a vehicle lamp of any ordinary or suitableconstruction and B the annular front frame which is movably attached tothe body by the usual hinge and catch and which may contain a reflectorlining b. The frame B is provided with the usual front glass 0.

D represents the lens or bulls eye which is arranged centrally withinthe front frame B in rear of the front glass so as to be approximatelyin line with the flame. This lens is secured in a circular, metallicframe E,

preferably by a wire ring 6, or other suitable means, so as to beremovable.

The lens frame E is secured to the annular front frame B by radial rodsF which are secured with their inner ends to the lens frame by solderingor otherwise, and

with their outer ends to the front frame B by screw nipples or sleevesG. The latter are threaded internally and engage the outer threadedportions f of the rods. The nipples extend inwardly through openingsformed in the front frame B and its lining or reflector b and bear withtheir heads against the outer side of the frame. By tightening orreleasing the nipples the position of the lens can be adjusted as may benecessary to aline it properly with the flame, and by removing thenipples the lens can be detached when not required for use.

I claim as my invention:

1. In a lamp, the combination of a lens, a surrounding supporting frame,supporting" rods connected at their inner ends with the lens, andindividual fastenings which connect the outer ends of the several rodsseparately with said frame and which are radially adjustable, therebyenabling the lens to be focused with reference to the flame,substantially as set forth.

2. In a lamp, the combination of a lens, a surroundingsupporting frame,supporting rods connected with the lens at their inner ends, andadjustable screw fastenings con- -necting the outer ends of the rodswith said frame, substantially as set forth.

3. In a lamp, the combination of a lens, a surrounding supporting frameprovided with openings, supporting rods arranged in line with saidopenings and connected with the lens at their inner ends, and screwsleeves arranged in said openings and engaging the outer ends of saidrods, substantially as set forth.

Witness my hand, this 10th day of November, 1905.
